Firefox is a great web browser
Firefox was the first browser to really give Microsoft's Internet Explorer a run for its money back in the early 2000's and made popular a number of internet paradigms we take for granted these days.
For a fascinating description of the rise of Firefox's popularity and the struggle for browser dominance in the 1990s and 2000s, check out the Wikipedia page on Browser Wars.
Firefox has tabbed browsing, great security, is standards compliant, wide platform support (it runs on lots of operating systems and devices) and a huge number of Addons to add extra functionality.
Firefox Extended Support Release
Mozilla - the company that creates Firefox - provides a standard release of Firefox which is updated fairly frequently. This is excellent for most users; particularly because by default, this version of Firefox will automatically update itself - helping keep its users safe and up to date.
However the process of frequently updating software can sometimes cause problems in more "structured" environments - particularly Corporations, Governments and Universities where they have hundreds or thousands of computers to support en masse. If software is updating itself, it can sometimes cause existing systems to no longer work properly, and sometimes newer versions of browsers will drop support for older web standards as well.
One way of preventing these problems is to simply not update Firefox any more - to keep Firefox at a version that's known to work properly. However the problem with doing this is that if you simply don't update Firefox then you also won't get access to Security and Bug fixes.
To help systems administrators in those Corporate, Government, Education (and other) environments prevent these problems, Mozilla also offers what is called an Extended Support Release (ESR) version of Firefox.
This is a version of Firefox which is "locked" at a major release version, as opposed to a version of Firefox which just updates itself to the very latest version available. The ESR Version of Firefox won't receive any new features and will continue to work in the existing, expected way. However, the difference is that the ESR Version of Firefox will also continue to receive new security and bug fixes during its extended support time frame.
Ordinary users don't need to use the ESR version of Firefox; you should stick with the Standard version of Firefox available from Mozilla, however Systems Administrators in those larger environments may find it useful to deploy the ESR version of Firefox for their users instead of the standard.
